Yes, I have purchased this. It is 6 inches from end to end. Screw holes about 4 inches apart.
The holes on this knocker are 3 15/16 on center.
The distance between the screw holes is 3 15/16" The total length of the knocker is abt. 6". It is solid brass with the satin finish. A template in the package is used to mark the holes for the screws which are drilled all the way thru the door and capped with washer covers. Need a 3/8" drill bit.
Mine came with a pattern to mark the screw holes.
